Multi-purpose convertible play yard

ABSTRACT

A co-sleeper convertibly adapted for use as a changing table, bassinet or play yard is described. The invention includes a first rigid enclosure that has four walls and a floor with the front wall capable of being positioned at an upper level equal to the remaining walls or at a second lower level. The first enclosure is capable of supporting a second enclosure within it that has four walls, a floor and can support a mattress. The co-sleeper is secured at one side of a parental bed with the co-sleeper mattress positioned a short distance below the level of the mattress of the parental bed. The front wall of the invention is placed in the second, lowered position for use as a co-sleeper or changing table and positioned at the upper level when the invention is used as a play yard or bassinet. The front wall has a fixed lower portion and a raisable upper portion. The upper portion of the front wall is formed as a rigid panel or as a flexible panel and various means are used to maintain the upper portion of the front wall in the upper position. The rigid panel may be hingedly attached to the first enclosure, slide in tracks, pivot or be completely removable. The rigid panel may zip in place or be maintained by a removable cross-rail secured in a passageway at the upper edge of the upper portion of the flexible front wall that attaches to the first enclosure front rails.

PRIORITY INFORMATION

This application is a continuation of U.S. patent application Ser. No.11/054,370, entitled “Multi-Purpose Convertible Play Yard,” filed Feb.8, 2005, which is a divisional of U.S. patent application Ser. No.10/043,702, filed Jan. 9, 2002, now U.S. Pat. No. 6,877,173, entitled“Multi-Purpose Convertible Play Yard,” the entire disclosures of whichis hereby incorporated by reference herein.

FIELD OF THE INVENTION

The instant invention relates to the field of convertible units for usewith babies and very young children; in particular to units which may beeasily converted from a play yard to a bassinet, changing table orchild's bed-side sleeping enclosure, hereinafter referred to forconvenience as a “co-sleeper”, that attaches securely to the parents'bed.

BACKGROUND

Furniture and fixtures for use by babies and small children oftenpresents a problem for parents with limited living space. For thisreason it is desirable that such furniture serve more than one purpose.A bedside co-sleeper is very useful for an infant or very young child asit prevents a parent from having to get out of bed to deal with a childrequiring minor attention or comforting. If the co-sleeper can then beput to other uses, the parents will save both space and the cost ofother furniture. If the co-sleeper can be folded for traveling it willhave additional utility. Various examples of such multi-purposechildren's furniture have been patented and sold.

In U.S. Pat. No. 5,349,709, issued to Cheng teaches a foldingcombination playpen and baby bed having an elevated floorboard. U.S.Pat. No. 5,339,470, issued to Shamie discloses a combination foldableplaypen and dressing/changing table. U.S. Pat. No. 5,553,336 issued toMariol adds an upper level to a playpen to provide a bassinet. The shortlegs of the upper level are inserted into openings in the top of thevertical supports of the playpen. U.S. Pat. No. 2,632,186, issued toBerk et al. discloses a portable combination crib and playpen. U.S. Pat.No. 2,691,176 issued to Saldana teaches a unit designed for home andtravel that may be used as a support for a playpen, bassinet or babychair.

U.S. Pat. No. 5,802,634 issued to Onishi, et al. describes an adjustablebed, suitable for use from infancy to adulthood that includes a bedframe body having pivoting end panels and a height adjustable base. Inone adjusted position, with the end panels pivoted to near vertical andthe height adjustable base fully raised, the bed is swingable like acradle, with the bed frame body swingably suspended from the heightadjustable base. By lowering the height adjustable base, the nearvertical end panels contact the floor, and the bed is useful as aplaypen for an infant or a chair for an adult. By pivoting the endpanels to intermediate or horizontal positions, the bed becomes usefulas a lounge chair or as a bed for a child.

Beside cribs that attached to the parents' bed were known at the turn ofthe century (U.S. Pat. Nos. 5,548,005; 620,069; 1,138,451; 1,283,169;1,267,244) but fell out of favor for many years. Recently there has beena resurgence in the practice of having babies adjacent the parents' bed.Such bed-side devices are taught in U.S. Pat. No. 5,172,435 to Griffinet al.; U.S. Pat. No. 5,148,561 to Tharalson et al; and U.S. Pat. No.5,293,655 to Van Winkle et al. Cox, U.S. Pat. No. 6,202,228, describes acrib securable to the side of a parent's bed that includes an alarmmechanism for sounding an audible alarm when an infant attempts to climbfrom the crib onto the parent's bed.

It is an objective of the present invention to provide a bedsideco-sleeper that can be adapted for use as a changing table, bassinet orplay yard. It is a further objective of the invention to provide aco-sleeper with these capabilities that is inexpensive, compact andportable. It is still a further objective of the present invention thatthe unit be simple to erect and collapsible for transport and storage.Finally, it is an objective of the invention that the co-sleeper designconsider and address all possible safety considerations related to itsuse. Other features and advantages of the invention will be seen fromthe following description and drawings. The present invention addressesmany of the deficiencies of prior art convertible sleeping unitinventions and satisfies all of the objectives described above.

Means areprovided for removably supporting the second enclosure within the firstenclosure at least one predetermined distance from the top of the firstenclosure. A securing strap assembly is provided for securing the playyard to a parental bed. When the front wall is in the raised firstposition and the second enclosure is supported by the supporting means,the play yard is usable as a bassinet. When the front wall is thenlowered to the second position, the play yard is usable as a changingtable. Further, when the securing strap assembly is properly positionedand the play yard is secured to the parental bed the play yard may serveas a co-sleeper.
